FIREARM.

To all whom it may concern:

Be it known that I, VVILHELM BRAUNING, a citizen of the German Republic,residing at Berlin, Germany, have invented new and useful Improvementsin Firearms, (for which I have filed application in Germany Sept. 28,1919,) of which the following is a specification.

This invention relates to the Brauning fire-arm and is of that type inwhich the breech-lock turns upward and carries the firing-lock withrearwardly projecting hammer or striker. The invention as compared withthis existing type of fire-arm, consists in that on the countersunk orset-back breech and lock-carrying bar there is secured an angle-piecewhich with its horizontal end extends to the breech-locking frameand'has a furcated upright portion to serve as a guide for the striker.This furcation consists in a bore for the passage of-the rear thickportion of the striker and of an upwardly extending slot to suit theadjacent thinner portion of the striker; said slot ending rearwardly inan enlarged recess forming a rest for the retention of the striker inits safety position. As a further improvement in accordance with thisinvention, the extractor is slidably mounted in the set-back of thebreech-bar and is kept, from dislodging, by the superposedbarrel-breech.

An embodiment of the invention isshown in the accompanying drawings, inwhich:

Figure 1 is a side view of the breech part with longitudinal section ofthe stock and showing the striker cooked and in safety position.

Fig. 2 is a corresponding plan.

Fig. 3 is a side view with the stock removed and the arm in itsafter-firing position.

Fig. 4 is a side view like Fig. 3 but showin the open breech.

igs. 5 to 7 are perspective views of details hereinafter described.

As clearly shown in the Figs. 1 and 2, the breech-lock 7c is made in theform of a frame of flat bar-iron in which is fixed the breech-block 71and the therethrough projecting striker b with its spring 7 The frame I:is hinged or pivoted to the breech-end h v of the barrel Z, saidbreech-end being firmly fixed to the breech-supporting bar s. Thebarrel-breech h is made of sharp-angled metal. The bar 8, made of flatmetal, car- 7 Specification of Letters Patent. Patent d D 27 1921Application filed April 30, 1921.

ries a fixed angle-piece 'w of flat metal hav ing an aperture to forguiding the rear thick portion 6 of the striker b. For cocking thestriker the head Z2 of same is pulled to the rear, when the percussionpin at the front end will be retained in cocked position by the usualcatch u of the detent a, see Fig. 3. The catch u is made by slitting theend of the detent u and then turning up the middle portion. Theprojecting fork like portions 14 are shaped to form bearings forcradling the lateral lugs 2 of the trigger a. The trigger is providedwith a tip a which bears against the detent and supports same in itsidle position as in Figs. 1 and 4. The trigger a is entirely made offiat metal in a stamping and bending or shaping operation. The apertureto of the angle-piece w communicates upward with an open slot of a widthcorresponding to the striker-portion forward of 6 thereof, so that incockmg the striker itsthinner portion passes up the slot and allows thebreech to be opened, see Fig. 4. Above the aperture 'w at the rear ofthe slot is formed a recess 10 into which the part b of the strikerengages aftercocking. The fire-arm is then cooked in safety position,see Figs. 1 and 2. By extending the horizontal forward end of theangle-piece w to contact with the breechframe 7:: the latter is lockedfrom the rear, while upward turning of same is prevented by theengagement of the striker-portion b in the aperture 20 of theangle-piece w, see

Fig. 3.

The extractor :12 consists of the base plate m and the'extractor-clawthe whole being made of flat metal by stamping and bending. Theextractor is shiftingly carried in the set-back s of the bar 8 and isheld above by the breech 71, of the barrel. Movement is imparted to theextractor, at opening and closing of the breech, in causing a suitablyshaped forward end or nose of the breechframe to engage in side slotsformed in the base plate m of the extractor. All locking parts togetherwith the lock and the barrel are carried by the supporting bar 8 towhich they are suitably fixed as and where required.

I claim:

1. Breech-mechanism for fire-arms which consists in a barrel with aconnected squareshaped breech-piece, an upwardly swinging breechlockingdevice, a striker mounted slotted and recessed at the rear of the slotto accommodate the striker in its different operative positions, a catchfor the striker, a trigger operatively connected with the catch, and anextractor for removing empty cartridges from the barrel.

3. Breech-mechanism for fire-arms consisting "in a barrel with asquare-shaped breech-piece, an upwardly swinging breech- ].oeking framehinged to the breech-piece, a striker mounted in said frame to projectendwise therefrom, an offset breech-supportin frame, means for lockingand releasing sald frame, a shiftable extractor bedded in the offset andcovered by the breech of the barrel, projecting lugs on the extractor, anose-piece connected with said frame for the engagement with-said lugsin operating said extractor, and means for retaining the striker atsafety and for firing the arm.
